We have identified a yeast nuclear gene (FMC1) that is required at elevated temperatures (37 degrees C) for the formation/stability of the F(1) sector of the mitochondrial ATP synthase. Western blot(More)
A cDNA carrying the Rip1 gene, which encodes the Rieske iron-sulfur protein of Schizosaccharomyces pombe, has been cloned by complementing the respiratory deficiency of a Saccharomyces cerevisiae(More)
We have analyzed the structure/function relationships of the yeast mitochondrial cytochrome b with a new methodology based upon the isolation of pseudo-wild type revertants from well-characterized(More)
Trp-142 is a highly conserved residue of the cytochrome b subunit in the bc1 complexes. To study the importance of this residue in the quinol oxidation catalyzed by the bc1 complex, we characterized(More)
Revertants of nonfunctional cytochrome b mutants were isolated and characterized to determine how specific deleterious mutations in cytochrome b can be suppressed by secondary mutations not restoring(More)
